Since I used this app a lot of my phone's data was stolen so I lost a lot. After using this app, my phone started to hang a lot. There is some antivirus app that could protect your smartphone indeed but not as well as they do to a computer or in your laptops. Because they just use your data and all that and when they do that you think it's cleaning the phone but it's not that. CM security is not cleaning your phone as you wanted no matter you download it or not nothing happens to your device either way. What antivirus does is it just increases your smartphone's speed little bit if you have downloaded the genuine app.
Do not download this app.
